A body with a mass of 2.75 kg is being spun by a piece of string in a horizontalcircle of radius 5.00 m on a flat, frictionless surface. It spins at a rate of 150rev/minute. What is the tension in the string (in kN)?

A massless string is wrapped around a cylinder of mass 0.400 kg and radius 0.100 m. The string is attached to the ceiling. The cylinder is released. As it falls, the string unwinds. What is the magnitude of the acceleration of the cylinder as it falls in m per s2?

A long string is wrapped around a 6.3-cm-diameter cylinder, initially at rest, that is free to rotate on an axle. The string is then pulled with a constant acceleration of 2.0 m/s2 until 1.3 m of string has been unwound. If the string unwinds without slipping, what is the cylinder's angular speed, in rpm, at this time?

A ball is tied to the end of a cable of negligible mass. The ball is spun in a circle with a radius of 2.00 m making 7.00 revolutions every 10.0 seconds. What is the magnitude of the acceleration of the ball?

A 70 kg person on a merry go round is spinning with speed 5 m/s. If they experience a centripetal force of 583N, how far from the center of the merry go round are they sitting? Express in meters.

You are on a Ferris Wheel that spins at 2.4 rpm. The ride is 29 m across. What is your apparent weight at the top of the ride if you have a mass of 64.2 kg?

A puck of mass m = 0.075 kg is moving in a circle on a horizontal frictionless surface. It is held in its path by a massless string of length L = 0.34 m. The puck makes one revolution every t = 0.65 s.What is the magnitude of the tension in the string, in newtons, while the puck revolves? The string breaks suddenly. How fast, in meters per second, does the puck move away?

A rock is spun in a sling at a constant speed of 56.0 m/s. What rate of rotation, in rev/s, is necessary to give the rock the required speed? Take the radius of the circle to be 1.75 m.

A 30.5-cm-radius tire on a moving car turns through 3π rad in 0.25 s. What is the speed of the car in kilometers per hour?

a marshmallow is placed 3.9cm away from the center of a rotating microwave plate for 0.6 minutes. if the plate rotates at 6.5 rpm, what is the tangential acceleration in m/s/s?
